i was at a jiffy lube the same day something similar happened to a customer the tech downstairs mixed up the tranny and oil drain plugs under a subaru forester and drained all the transmission fluid not realizing the mistake the guys upstairs filled the crankcase up with another gallon of oil i imagine if theyd have checked the dipstick they wouldve noticed something was wrong but they just sent that guy out the door i think he made it about feet out of the parking lot
